ERNEST PAILLARD, OF SAINTE-CROIX, SWITZERLAND, ASSIGNOR TO M. J. PAILLABD & GO., OF NEW YORK, N. Y.

MUSICAL BOX.

SPECIFICATION forming part of Letters Patent No. 268,273, dated November 28, 1882. v Application vled May 6, 1982. (No model.) Patented in Germany July I1. 1881, No. y27,520.

To all whom it may concern Beit known that I, ERNEST PAILLARD, of Sainte-Croix, Canton de Vaud, Switzerland, have invented certain new and useful Improvements in Musical Boxes, (for which I obtained a patent in Germany, No. 27,520, and bearing date the 11th day of July, 1881,) of which the following is a specification.

The improvements in musical boxes forming the subject of this invention relate to the retaining ratchet and pawl of the spring-arbor, the spring-drum, .the speed-regulating gear, the tune or air changer, and the pin-barrel shaft. The retaining-pawl of the .driving spring-arbor is stamped out from a comparatively thick piece of sheet-steel, and is so shaped as to have sufficient elasticity to spring sidewise into the notches of the ratchet-Wheel without requiring hardening and tempering. -lt is secured to the side of and located in an opening formed through the bevel-wheel which is on the arbor, and imparts the power of the mainspring to the pin-barrel. The spring has a projection on its side, which its into a notch, forming part of said opening in thc bevelwheel, in line with the direction of strain exerted on the pawl by the ratchet-wheel, said ratchet-wheel being secured to the arbor in close proximity to the bevel-wheel.

'The improvement in the spring-drum consists in making it of sheet metal, stamping it out in the desired shape, and then drawing it into proper form, all of the holes therein for the screws which secure the drum to the frame, Snc., for the arbor and other bearings, being punched at one time. The retaining-hook for lioldingth'e end of the mainspring is also a part ofthe drum, and is formed by cutting and bending inwardly an angular piece from the side of the drum. By this arrangement the spring-hook never becomes loose, nor is it liable to break, as do land are the hooks which are riveted in the side of the drums as heretofore made. Y Besides, these drawn-metaldrnms are stronger and cheaper than those of cast metal. of all the holes being made in them at one 0peration, thus saving time in putting up the movements and in making repairs.

They are perfectduplicates on account In the train of wheels ofthe regulating-gear 5o of musical boxes heretofore made considerable noise is produced on account of the high speed of the fan, 85e. This noise I eliminate by using a much larger fan and a lighter fly-wheel and running them at a lower speed, which I am enabled to do by certain rimprovements in the wheel and pinion bearings, they all being stamped ont an'd formed up of sheet metal, and a further'saving is had in obtaining the desired resulty by using one less wheel and pinion in the train; and the pin-barrel shaft is formed with taper end, which is supported in an adjustable screw.

I will now refer to the accompanying drawings to more fully explain the construction and operation of my improvements in musical boxes. v

Figure l is a plan view. Fig. 2 is a side elevation, with the spring-drum in section. Fig. 3 is an end view. Fig. et is a part side elevation, showing the air-changer in operation. Fig. 5 is a plan sectional view of the springdrum. Fig. 6 is an underneath view of the bevel-Wheel, showing the retaining pawl and ratchet; and Fig. 7 is a plan view ot' the fan as stamped out and before being bent into shape. y

The main-frame a and combV of keys b are substantially of the ordinary construction. At one corner ot' thel main frame a is a recessed projection, on which is secured the spring-drum c by means of the screws c c', passing through its tlange. These screw-holes, as Well as the central hole for the bearing of the upper end of the arbor d and the hole for the stud of the winding safety device d', which is of the ordinary construction, are formed in the drum, after it is drawn into the shape shown, at one operation. Y

v In the side ofthe drum c is cut and pressed 9o inwardly an angular piece, c2, which forms the hook for holding the outer end of the mainspring e, as shown in Figs. 3 and 5, and the inner end of the spring c is held by a hook on the arbor d. Immediately below the drum c is the bevel-wheelf, tted to turn on the arbor, and below the bevel-wheel, rigidly secured to the arbor, is the ratchet-wheel or notched disk g. These are locatedin the recess of the projection on which the drum eis secured, and the arbor d has its lower bearing in the bottom of the recess and extends beyond the bottom of the main frame, where it is provided with the winding-key cl2, screwed thereon.

On the under side ofthe bevel-wheel f is secured by the set-screw h the spring-pawl h, which is cut out of comparatively thick sheetsteel in the shape shown at Fig. 6. It is bent upintoacorrespondingly-shaped opening made through the bevel-wheel f, and its end h2 is bent down to catch sidewise into the notches of the ratchet-wheel g, and on the side of the spring, in line with the thrust of the ratchetwheel on the end h2, is formed the projection h3, which bears' against the side of a recess formed inthe opening in the bevel-wheel, so that none of the strain of the mainspring e is felt by the spring part ofthe pawl h, which is between the projection h3 and the holdingscrew h', and which is made suiiciently long to impart to the pawl resilience without necessitating hardening and tempering the same. By this construction I am enabled to obviate one of the principal sources of trouble of this class of instruments, as the retaining-springs and the pawls of the same, as now made, are continually breaking.

The shaft i ot' the pin-barrel j is fitted at one end to rotate in a bearing made therefor in the side of the spring-drum c, and its other end is pointed and rests in a conical hole in the end of the adjustable screw i', tted in the standard i2, projecting up from the main frame a. On this shaft 'i is secured the bevel-pinion ff, meshiuginto the bevel-wheelf, and the gear` wheel m, which meshes into the pinion m', secured to the side of the intermediate wheel, n, which imparts motion by the pinion n on the spindle or shaft n2 to the fly-wheel o. 'The pinion m' and wheel n rotate in bearings in the frame n3, as does also one end of the shaft n2. The otherend of this shaftworks in the frameoz. Above the fly-wheel ois located in a horizontal position the fan-spindle p, on which is cut the screw o', into which works the teeth of the ilywheel o. One end of the spindlep is pivoted in an arm forming part of the frame o and as this endis the thrust end asimple anti-friction bearingis provided forit by slotting the arm at right angles to the spindle p and inserting therein a small piece of hardened steel, p', against which the end ofthe spindle bears. The other end of .the spindle p has a bearing in the bracket-frame p2, and on it, between this frame and the fly-wheel o, is placed the fan q. This fan q is much larger than ordinarily, and is cut from thin sheet metal, as shown at Fig. 7. The connecting-pieces g q being centrally perforated, they are then bent at right angles to the resisting-planes q, and the spindle p', which is slightly taper, is passed through their central holes, as shown at Fig. 1. The adjustable screw i allows the barrel j to be readily removed and all end-play of shaft i to be taken up. By this arrangement of the speed-regulating gear I eliminate an intermediatewheel and pinion, as required in the regulating-gear of musical boxes heretofore, saving the friction due to the same, which enables me to make the fly-wheel 'lighter and the fan larger, whereby the speed of the pin-barrel is maintained uniform and The change of tune or air is accomplished hy V the barrel j being moved into different longitudinal positions on its shaft t', for which purpose it is iitted freely ou the shaft i, and is caused torotate therewith by the carrier j', secured to the wheel m in the ordinary manner. Between the wheel m and the end of the barrel jon the shaft i is placed the spiral springjz,

which keeps the other end of the barrel against my improved air-changer. This air-changer consists simply of the cog-plate r, fitted to turn freely on a screw-stud on the standard 112 at right angles to the axis of the barrel.

The teeth of the cog-plate 1 are of different lengths, and their ends are tlat, and the end of the barrel bears against the end of the tooth adjacent thereto, as shown at Figs. l and 2, it sliding on the end of the tooth until the short pin s, projecting out from the end of the barrel, comes in contact with this tooth, thereby turning the cog-plate fr round and bringing the succeeding tooth against the end of the barrel, the barrel having a depression, s', just behind the pin s to allow the front corner of the tooth to catch therein as the cog-plateis bein g'turned, as shown at Fig. 4, to insure the end of the tooth assuming a flat position with the end of the barrel. Four teeth are shown in the cog-l plate r in the drawings, the diametrically-opposite ones being of the same length, so that only two positionsare assumed by the barrel j. Consequently with this air-changer the instrument is adapted to play only two tunes or airs. have three teeth of different lengths, or six teeth having three different lengths, arranged,

For a three-air changer the plate will it' desired, to repeat each or any of the airs, or

construction may be modified and their posi-4 tionsin relation to one another may be changed Without departing from the nature of my invent'ion-as, for instance, the air-changer may be placed at the other end of the barrel, either to'work against a flange attached thereto or against its end, and the barrel-spring placed to act against the other end, and the springdrum and arbor may be placed at right angles to the position occupied by them, as shown, and motion imparted to the pin-barrel by 'straight Wheels instead of bevel-wheels.
